In recent years there has been increased interest in the shock wave/flame interaction, which occurs in many combustion systems, such as power plants, gas turbines and engines etc. shock wave/flame interaction is also detected when unwanted fire or explosions occurs in some industrial activities. In a combustion system, due to turbulent burning following the interaction of unburned gas with the walls or obstacles, a flame front velocity increases and a shock wave is formed. Flame velocity is further accelerated by the subsequent shock wave/flame interaction, and then there even leads to explosion or detonation[1]. In the interaction process, it is known as that Richtmyer-Meshkov instability plays an important role more than laminar and turbulent burning. Richtmyer-Meshkov instability is one of the basic phenomena of the supersonic combustion and an important mechanism for transition to turbulent flame[2][3]. |
